Well, basically the demo has received multiple changes just because I kinda forgot to change several things, such as removing the hitboxes for debugging purposes. I also added a few things just from demo feedback. Anyways, I just want to list out the things I added since the pre-demo version of the game. There's really a lot I added.

HUD with animated character portraits for the currently available characters and assistants

3 working stages with appropriate backgrounds

The ability to recruit assistants by aiding them

Xbox 360 controller support

A working spawn for the common, aggresive type enemy

A dash feature, which also comes with a dash cancel tech (this changes the game's meta actually)

Character balances

Healing orbs

Changed boss portraits

Boss HUD

Assist HUD that changes depending whether you're playing one or two players

A game over screen

A title screen

A user friendly, character selection screen

Chapter starter

A player select screen that has an Xbox 360 controller detection system

A windowed, fullscreen selection game starter

Team logo at the start of the game

Gave appropriate sprites for the first boss

Revised dialogue to sound less cringy

Death animation for Derek

Fixed second player controls

Fixed UNLEASH bugs

I will no longer update the demo version, but I've been updating the full version. So far, all I've added though is just a scrolling text along with different beeping noises depending on the character speaking and a new, animated portrait for Naira's dialogues.
